In their conversation they also talk about how Metatron is not on Michaels side anymore. Something that seems to be sorta news to Uriel. Metatron says he should have heard it from Zachariel. The same angel who is smirking through the meeting, perhaps he likes to gossip a bit about how things are going down for Michael, at least making it more obvious for people. He even said ‘you of all people’ when Metatron offered his help to Michael. I don’t know if that was what triggered Michael to send in Jeanne on his own or not but it was after that sentance. Perhaps he intentionally reminded Michael of what had happened there. In either way Michael doesn’t trust Metatron at all. Metatron having ‘left Michaels faction’ is the more proper fact I can get out from it. Metatron confirming that they are not on the same side during a council. For two beings who used to be close friends to end up like that is what could be seen as a betrayal. Michael can’t trust him.
